Andrew, Thanks for pulling this together, and thanks Bill, for providing these clips!
Is it most typical for American Bitterns to produce these paired calls during migration, or do they often just do single isolated notes? This is very helpful! Thanks again!

This is certainly the best recording I have, I am not sure and have not yet checked if others exist in Macaulay or Xeno-Canto.
